WHEEL-HUB.

SPECIFICATION forming partof Letters Patent No. 773,534, dated November1,1904,

Application filed April 1, 1903- .To all whom, it may concern.-

Be it known that LFRANK M. AsHLEY,a citizen of the United States, and aresident of New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Wheel-Hubs, ofwhich the following is a specification.

This invention relates to vehicle-wheels, and involves more particularlya novel combination of the spokes with the hub, whereby both the hub andthe spoke engagement therewith will be of great strength and the spokesheld in locked abutting relation.

The invention also comprehends a peculiar arrangement whereby the spokesare locked and mutually abut both within and exterior to the hub.

There are other important features and details connected with theinvention which, besides those alluded to, are clearly explained in thesubsequent extended description.

In the accompanying drawings, forming part of this specification, Figure1 is an exterior view of a hub embodying certain features of myinvention. Fig. 2 is a central longitudinal sectional view of the hubdisclosed in Fig. 1. Fig. 3 is a transverse section of the hubrepresented in the preceding figures, the section being taken in theplane indicated by the broken line 00 00, Fig. 2. Fig. 4: is a view ofthe hub as represented in Fig. 3, with the addition of the spokesinserted and locked in position.

Similar reference characters designate corresponding parts throughoutthe figures of the drawings where they occur.

D refers to a metal sheathing or casing in a single piece, constitutingthe exterior of the hub and having annular flanges A A projecting fromits central portion, sockets B B being formed between said flanges forthe reception of the base portions (6 of the spokes. A wooden core O isforced into the sheathing D, and this core contains a series of radialmortises, in which the spoke-tenons e e bear. The metal segmentsspanning the space between the flanges A A form bridges, as indicatedmore particularly in Fig. 3 by ff, said bridges having roundedcontractions g at their Serial No. 150,579. (No model.)

inner sides forpermitting the base portions a of the spokes E to expandwithin the bottoms of the sockets, as indicated-in Fig. A, to an extentthat will lock the spokes in position and resulting in their baseportions coming together at a point within said contractions, andthereby forming an inner ring G, presented by the continuously-abuttingportions of said bases. It will be seen that the spokes are soshouldered as to also mutually abut in a plane exterior and immediatelyadjacent to the bridges f, said abutting shoulders constituting a secondand outer ring H, encircling the hub and confined between the flanges AA thereof. It will be noted that the abutting portions forming the innerring are correspondingly confined.

By reference to Fig. i the parts are so proportioned thatclearance-spaces t' are presented immediately at the inner sides of theabutment-rings H. The presence of these spaces insures the partsconstituting the rings coming into proper abutting relation, and thesaid spaces additionally serve to relieve the bridges f of undue strain.

I do not desire to be understood as limiting myself to the particularfeatures or arrangements of parts shown and disclosed, but reserve theright to all such modifications as may be fairly within the scope of myinvention.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- 1. A metallic hub sheathing integrallypresenting annular flanges and intervening bridges conjointly formingradial spoke-sockets, said bridges having inner rounded portionsterminating short of the bottoms of the sockets.

2. In a hub, the combination with a wooden core, of a sheathingintegrally presenting annular flanges and intervening bridges conjointlyforming radial spoke sockets, and spokes within said sockets, and havinginner laterally-enlarged abutting parts in locked engagement with thebridges.

3. In a hub, the combination with a wooden core, of a sheathingintegrally presenting annular flanges and intervening bridges eonjointly forming radial spoke-sockets, said bridges having inner roundedportions terminating short of the bottoms of the socket and outersurface of the core, and spokes within said sockets and having innerlaterallyabutting parts closely conforming to the inner rounded portionsof the bridges and in locked engagement with the latter.

4. In a hub, the combination with a wooden core, of a sheathingintegrally presenting annular flanges and intervening bridges conjointlyforming spoke-sockets, and spokes within said sockets and having outerand inner abutting parts, the outer parts forming a ringabutmentexternal to the bridges and the inner parts in locked engagement withthe inner portions of the bridges.

Signed at New York, in the county of New York and State of New York,this 25th day of March, A. D. 1903.
